A couple days ago I put the heptagonal prism on shapeways. Its a really nice cube to solve and its looks really great. The turning of the puzzle is of course fantastic because the donor cube is a 50 mm dayan zhanchi. You'll have to truncate the donor cube a little bit for extra info about the truncations see the sw puzzle. Also if you have the 2x2 heptagonal prism this I a great edition to your collection.
